That doesn't surprise me, if you look at the MSDS you will see that it includes as much as 5% nitric acid, 5% copper nitrate, as well as really toxic stuff such as selenium dioxide, as much as 10%. Definitely wear gloves when using this.
Ballistol of course, don't mention this, merely stating that it has ammonia plus "very special compounds", and even recommend plugging your barrel, filling it up with it and leaving it overnight. Hmm.
They also say that "
Steel, chrome and nickel are not attacked by Robla Solo MIL." Somehow I doubt that. Carbon steel for example is strongly attacked by nitric acid.
Knowing a bit of chemistry, it could be potent stuff.
Ballistol would be useful to neutralise any traces, being alkaline. It is actually mostly just liquid paraffin AKA baby oil, together with soap to help it emulsify with water (alkaline salts of oleic acid), benzyl acetate (Jasmine scent), and some sort of vegetable seed oil. Not much use as a gun cleaner, but as a preservative, maybe. I honestly don't understand its reputation as being much use otherwise. Or drink it as a laxative I suppose.

I'll just stick with my trusty ammonia-containing Butch's Bore Shine, which seems to do pretty well on carbon and copper, since I have a large bottle of it and a little goes a long way. Also they make full disclosure in their MSDS as to the ingredients. I see nothing in there likely to attack steels. If its good enough for Callum Ferguson it'll do for me.
